IN VENTOE ite SEALER Gr-MACHIN E.

To all whom it may concern:

Be it knownthat I, ALBERT S. KUX, a citizen of the United States residing in Chicage, in the county of 00k and State of Illinois, have invented certain new and useful Improvements in Sealing-Machines, of which the following is a specification.

My invention refers to merchandising and particularly to a novel means of utilizing gummed paper. strips for securing the wrappings of bundles and the like.

Among the various means of securing wrapp'ings of packages bundles and the like is the means of employing strips of paper having adhesive material on. one side and mounted so that strips of different lengths might be taken therefrom for application to bundles of varying sizes. In a device for providing gumn'ied strips as above described the strip is usually furnished in a roll and suitably mounted in a frame work so that the free end of the strip may be led over a moistener which generally is in the form of a roller the lower part of which is in water and over which the strip passes to be moistened by the rotation thereof as it is pulled thereover. It has been found that when a portion of the strip is torn off for use that there is no portion of the remaining strip available to be grasped by the operator when a new portion is desired. Under such conditions the operators fingers become moistened and consequently the bundle which he is wrapping becomes wet or perhaps soiled. To overcome these and other well known objections, I have devised a novel means for feeding the strip forwardly a suflicient distan'ce so that the end thereof may be grasped by the operator without bringing his fingers in contact with the moistening roller-and at the same time provide means to press the strip against the roller so that the gunnned portion may be sufliciently moistened for ap plication to the package. Another object is to provide a feeding mechanism and means for directing the strip against the moistening roller so that cooperation therebetween may be effected. V

A further object is to provide a feeding mecl'lanism and a pressing mechanism so associated that the pressing mechanism will not force the strip against the moistening roller whilethe strip is being fed. forwardly by the feeding mechanism.

These and other objects of my invention will be more readily understood by reference to the drawings, wherein,-

Fig. 5 is a section on line-5 5 of Fig. 3.

The device consists of a frame member 10 having supports 11 and 12'. The support 11 is continued upwardly above the top of the frame member 10 to form a shoulder 13 carrying bearings 1 1. Mounted within the bearings 14L is a roller 15 on shaft 14 which carries the gummed paper strips 16. "Mounted on the frame member 10 in suitable bearings 17 is a roller 18 and cooperating with the under side thereof is a spring 19 for guiding the strips 16 against the under side of the roller 18. Positioned at the. forward endcf the frame member 10 a moistening roller 20 mounted in suitable journals 21 and adapted to rotate within a compartment 22 in which water is placed.

011 the lower portion of the forward support 10 is pivoted the feeding mechanism which is formed of a substantially U-shaped member having legs 23 and 2 1 pivoted at 25 to the supports 12. The legs 23 and 24s are connected by top member 26. Pivoted to thelegs 23 and 21: is a frame member having side members 27 and 28 and cross member 30, the pivotal connect on being at the upper portion of the U member at the point 31. An operating lever 32 may be attached to the .member 30 if desired for the actuation thereof. A spring 33 connected to the side member 27 at 3% and at the outer end to an extension 35 on the frame member 1() acts to maintain the feeding mechanism in retracted ornormal position. For preventingforward movement of the upper member off the feeding mechanism beyond the point that is desirable Shoulders or other suitable steps may be provided on the members 2?),

and 27, 28.. Pivoted on. the frame 10, or p the legs 12 is the presser bar which comprises side members 35, 36, and cross or presser member 07. A. spring 38 connected to the side bars 35, 36, and at the other end attached to the frame'member 10 serve to held the cross bar 37 against the upper surface of the moistening roller 20. Mounted on the frame and positioned slightly in the rear of the moistening roller 20 are guides 39 being provided with spaced rear edges to direct the gummed strips therethrough and constricted at their front-edges forming an opening to serve as a cutting edge when a portion of the strip is torn off. As shown in Fig. 2 the inner portions of the arms 23, 2d, are provided with lugsdO carrying set screws -11 adapted to bear against the arms 35, 36, of the presser member so that when the feeding mechanism is moved forwardly theset screws will cause the presser bar 37 to be raised from engagement with the moistening roller 20. Proper adjustment of the set screws 41 will determine the instant at which the presser bar 37 is removed from the roller 20 and how long it is held away therefrom during the time of operation of the feeding mechanism.

Mounted on the shaft is for vertical adjustment against the spool 15 are guide members l2 which are provided with vertically disposed slots to overlie the shaft is on which the spool 15 rotates and are provided with spring member 4E3 adapted to hold the guides 42 against the roll of gummed strips 16. i For positioning the guides 42 on the shaft 14E to accommodate different widths of paper strips knurled members 44 are pro vided which will adjustably position guides &2 on the shaft 14L.

The operation of the device is as follows:

Strip paper 16 wound on spool 15 is mounted on'the shaft 1? and the shaft insorted in the shoulders 14. The free end of the strip is then fed through underneath the roller 18 between the roller and its spring pressed guide 19 forwardly between the member 30 of the upper portion of the feed ing mechanism and the upper bar 26 of the lower portion, thence between the guides 39 and underneath the bar 37 of the presser member. Portion 16 of the strip then eX- tends beyond the presser member 37 and is ready to be grasped by the operator. WVhen the portion 16 has been torn off as shown in Fig. t by raising the portion 16 against the cutting edge on the guides 39 the front end of the strip l6v will be at the cutting edge ofthe 'guides'39 behind the presser roll 37 and in an inconvenient place to be grasped by the operator. The handle 32 of the feeding mechanism is then moved forwardly quickly. The movement of the upper portion of the feeding mechanism causes thestrips 16 tobe grasped between the upper member 26 of the lower portion and the lower member 30 of the upper portion thereby feeding the whole strip 16 forwardly through the guides 39. The instant the feeding mechanism is moved forwardly the presser bar is raised from against the moistening roll 20 so as to permit the ends of the strips 16 to be moved forward freely. VJhen the feeding mechanism is in its forwardly position as shown in Fig. 3 the handle is released and the springs 33 quickly move the feeding mechanism back to normal position as shown in Figs. 1 and 4t, leaving the strip advance as shown in Fig. 1 with a free end 16. The movement of the feeding mechanism to normal position permits the presser bar to be moved against the upper side of the strip 16 and thus when the strip is pulled forwardly by the operator will cause the roller 20 to turn and moisten the under side of the strip 16. The cooperation between the presser bar 37 and the roller 20 is essential so that the pulling forward of the strip 16 by the end member 16 will cause the roller :20 to turn and thus moisten the under side of said strip. Furthermore, the return of the feeding mechanism must be accomplished quickly for if a restraint be placed on the handle 32 while the mechanism is allowed to return to normal position, the strip 10 will be moved backwardly as the gripping between the members 28 and 30 will continue as long as any pressure on the handle 32 remains.
